If you need to create a feature group with vector similarity search supported, refer to [this guide](../vector_similarity_search.md#extending-feature-groups-with-similarity-search). `name` is the only mandatory parameter of the `create_feature_group` and represents the name of the feature group. 
 
 In the example above we created the first version of a feature group named *weather*, we provide a description to make it searchable to the other project members, as well as making the feature group available online.

-Then, add one or more embedding features to the index. Name and dimension of the embedding features are required for identifying which features should be indexed for k-nearest neighbor (KNN) search. In this example, we get the dimension of the embedding by taking the length of the value of the `embedding_heading` column in the first row of the dataframe `df`. Optionally, you can specify the similarity function among `l2_norm`, `cosine`, and `dot_product`.
